Murray and Sears have also been spotted in the front row of Burberry's London Fashion Week show in the past, while chief creative officer Christopher Bailey recently praised Murray in a BBC documentary.

Manager Simon Fuller - who also works with the Beckham family - is said to be organising a deal for the couple to lead a new campaign with the fashion giant, according to the Daily Mail.

Sienna Miller and Tom Sturridge are currently fronting a similar campaign, while other past non-romantic couples to do so include Eddie Redmayne and Cara Delevingne, and Rosie Huntington-Whiteley and Sam Riley.

A spokesman for Burberry said in a statement: "We never comment on campaigns until they are announced."
